SPECIFICATION forming part of Letters Patent No. 757,960, dated April19, 1904. Application filed April 3, 1903. Serial No. 150,986. (Nomodel.)

To all whom, it may concern:

Be it known that I, HIRAM W. PHILLIPS, 0 Quincy, in the county ofNorfolk and State of Massachusetts, have invented a new and usefulImprovement in Pile-Driving Apparatus, of which the following, taken inconnection with the accompanying drawings, is a specification.

My invention relates to that class of piledrivers that are used fordriving piles under water, and especially in locations in which thewater is comparatively very deep and the heads of the piles are sodeeply submerged as to be beyond the capacity of the ordinarypile-driver.

The apparatus is necessarily mounted upon a scow, float-stage, or otherdevice for holding it steady while working; and it consists in combiningwith a suitable supporting-frame a telescopic adjustable tube comprisinga fixed member and one or more adjustable members constructed to serveas a guide for the piles and devices for controlling the said tube.

It also consists in several minor arrangements, the exact nature ofwhich will be fully set forth.

The object is to construct a reliable apparatus by which piles may beaccurately placed and readily driven in deep water. This object I attainby the mechanism shown in the accompanying drawings, in which Figure 1shows in side elevation a scow having a complete pile-driving apparatusincluding my improvements. Fig. 2 is a front elevation of the same. Fig.3 is a vertical section showing the arrangement of the telescopic tube.Fig. 4c is a horizontal section of the said tube, taken on line 4 4 ofFig 3. Figs. 5 and 6 show details in elevation and vertical section.

I have shown my apparatus as erected on a scow A, which hashoisting-engine B B B and a derrick C C C All of these are of ordinaryconstruction and need not be described in detail.

The pile-driving apparatus consists of a framework, of which D D arebase-beams firmly bolted to the scow and braced by beams D D and alsostayed by a cross-tie D The standards E E, which serve as guides or waysfor the supplemental or auxiliary guide for the immediate control of thehammer, are firmly connected to the beams D D and have a cross cap-pieceE and cross-ties E E The braces F F serve to hold the standards E E and,with the cross-bar F, to give the whole frame the required strength andfirmness.

A novel feature of this apparatus is the pile guiding and holdingdevice, which consists of a telescopic tube H K. This tube consists ofan outer tube H, which is detachably connected to the scow by the baseof the framework and by guy-ropes G G G which are attached to the outertube H at H H H H H H H are four guide-rollers located inside of thetube H and near the lower end. (See Figs. 3 and 4.) The inner tube K hasalso four guide-rollers K, two of which are shown in Fig. 3. This innertube K slides freely up and down in the outer tube H and is guided bythe rollers H and K. A hoisting-rope K Figs. 1 and 3, is attached to thelower end of the inner tube K at K and is operated by the drum B of thehoisting-em gine. A series of openings K K are made in the inner tube Kto admit of the free escape of the water as the hammer operates. Thistube is also weighted, so as to sink in water. The telescopic tube H Kmay when not in use be drawn up by the derrick and laid upon the deck ofthe scow, connection being made by the hook C and the eyebolt at Anothernovelty of my apparatus consists 8 5 in a supplemental guiding-framethat is construeted for the immediate control of the hammer W andconsists of a frame L L L L L L (SeeFigs. 2, 5, and 6.) This frameslides between the standards or ways E E, its downward motion beinglimited by the stops L L*, Fig. 2, permanently attached to the standardsE E. The upper end of the hammer W is made tapering, as shown in Fig. 6,so as to engage with the cleats L L at the top of the guiding frame, andthus prevents it from passing beyond the upper edge of the supplementalframe and also to cause the hammer in its upward passage to take theframe with it. The hammer W is operated by the fall W,

and blocked. A pile of such length as is desired to be driven is put'into the inner tube. The hammer, with its guiding-frame, is caused todescend. When the lower end of the hammer enters the upper end of theinner tube, the guiding-frame is arrested in its descent by stopsfastened to the standards. The hammer leaves the frame and goes downinside the inner tube, pushing the pile ahead. When the hammer is halfway or more througlr the tube, it is stopped, and the tube is lowereduntil its lower end touches bottom.

The hammer is then allowed to drop. The hammer fall being marked and thedistance between the face of the hammer and mark on the fall beingknown, with proper care piles may bedriven sufficiently accurate so asto eliminate the necessity of sawing them off after being driven. Wherethe water is sufliciently clear, a straight-edge having a spiritlevelfastened to it may be used as a guide, one end of the straight-edgeresting on a pile which has been driven to the desired grade, the otherend of the straight-edge placed beside the lower end of the inner tubeat an elevation known to be correct, as shown by the spirit-level. Thepile can be seen through the water-escape openings, and when the head ofthe pile is down to the required grade a signal is given and furtherdriving is discontinued. The work is usually performed in connectionwith a diver.

I claim 1. In a pile-driving apparatus: a hammer and means for operatingit; a supplemental guid- The hammer and its guid-' ing-frame, open atits lower end to allow of the passage of the hammer, constructed toslide between and to be guided by the main standards, and having topcleats adapted to engage with the upper end of said hammer whereby thesaid hammer in its ascent takes the said guiding-frame with it; andstops attached to the main standards, constructed to limit the downwardpassage of the said guiding-frame; substantially as and for the purposeset forth.

2. In a pile-driving apparatus: a hammer, and means for operating andguiding the same; a telescopic tube, adapted to receive and direct thepiles, extending from the base of the pile-driver downwardly, said tube'comprising a main tube and one or more extensions constructed to extendto the required length, and

means for operating said tubes; substantially as and for the purpose setforth.

3. In a pile-driving apparatus: a hammer and means for operating it; asupplemental guiding-frame, open at its lower end to allow of thepassage of the hammer, constructed to slide between and to be guided bythe main standards, and having top cleats adapted to engage with theupper end of said hammer whereby the said hammer in its ascent takes thesaid guiding-frame with it; stops attached to the main standards,constructed to limit the downward passage of the said guidingframe; anda telescopic tube, adapted to receive and direct the piles, extendingfrom the base of the pile-driver downwardly, said tube comprising a maintube and one or more extensions constructed to extend to the requiredlength, and means for operating said tubes; substantially as and for thepurpose set forth.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, on this 30th day of March,

HIRAM W. PHILLIPS. Witnesses:
